Camel route setup over camel-restlet component is returning incorrect content type header i.e "Content-type" instead of "Content-Type"""

HI Team,

We have setup the camel route over camel restlet for processing incoming http request requests but while returning the HTTP Response the http client is getting incorrect header name "Content-type" instead of "Content-Type".

When we deploy same web service over spring or cxf then we are getting correct header name in HTTP response.

 

Steps to reproduce:

1.Deploy restlet service.

2. Call the rest service using http client "SoupUI" or Postman and check the response headers.

 

Response Return by camel-restlet:

Tue Nov 26 12:27:33 GMT 2019:DEBUG:<< "HTTP/1.1 200 OK[\r][\n]"

Tue Nov 26 12:27:33 GMT 2019:DEBUG:<< "Server: Restlet-Framework/2.3.12[\r][\n]"

Tue Nov 26 12:27:33 GMT 2019:DEBUG:<< "Date: Tue, 26 Nov 2019 12:27:33 GMT[\r][\n]"

Tue Nov 26 12:27:33 GMT 2019:DEBUG:<< "Content-type: application/xml[\r][\n]"

Tue Nov 26 12:27:33 GMT 2019:DEBUG:<< "Content-length: 139[\r][\n]"

Tue Nov 26 12:27:33 GMT 2019:DEBUG:<< "[\r][\n]"

 

Response Return by spring:

Tue Nov 26 12:31:43 GMT 2019:DEBUG:<< "HTTP/1.1 200 OK[\r][\n]"

Tue Nov 26 12:31:43 GMT 2019:DEBUG:<< "Date: Tue, 26 Nov 2019 12:31:43 GMT[\r][\n]"

Tue Nov 26 12:31:43 GMT 2019:DEBUG:<< "Content-Type: application/xml[\r][\n]"

Tue Nov 26 12:31:43 GMT 2019:DEBUG:<< "Content-Length: 139[\r][\n]"

Tue Nov 26 12:31:43 GMT 2019:DEBUG:<< "Server: -[\r][\n]"

Tue Nov 26 12:31:43 GMT 2019:DEBUG:<< "[\r][\n]"

 

We have tried to set correct header name on exchange object but still camel is overriding it.

 

Questions:

1. Is there way to override the content type header name?
2. Is this known issue in camel? if yes, do we have resolution available in any latest version?
